1W, mm, f7??? W JOHN GODFREY PARRY THOMAS, or CHISWICK, LonnoN, ENGLAND.

To all whom it concern Be it known that I,.JOHN smatterin THOMAS, asubject of the King of Great.

Britain, residing at 21 Ennismore avenue, Chiswick, in the county ofLondon, England, have invented new and useful Improvements in theSuspension of Rail-Car Bodies and the like, of which the following is aspecification.

This invention relates to the suspension of rail vehicle bodies onbogies and has as its object the attainment of an efficient suspensionwith a cheap and light constructiom According to the invention leverswhich at one end support the center plate of the vehicle body and at theother end the edge of the body, are pivoted upon the bogie main frameand springs are interposed between the center plate and these levers.Preferably the levers are so arranged that a tilting of the vehicle bodytoward one side causes the center plate and the whole body to be shiftedtoward the opposite side, with the result that the weight tends to beevenly distributed between the two sides.

A preferred construction according to the invention is illustrated inthe accompanying drawings in side elevation in Figure 1, in endelevation in Fig. 2, and in plan in Fig. 3, Figs. 2 and 3 being halfviews, and all the'views showing only so much of the vehicle as isnecessary to make clear the nature of the invention.

In the accompanying drawings, 1 indicates the side members of the bogieframe supported upon springs on the wheel axles. These carry brackets 2which support the pivots of bell crank levers 8. The outer ends of theselevers 3 carry rollers 4 with ceive a pivot pin 8 which may be calledthe king pivot and which is attached to the body bolster or main frame9. This main frame has at its edges bearing plates 10 in position tocontact with the rollers 4:-

It will be understood that the weight of the vehicle is divided betweenthe socket plate 7 and the two rollers 4 accordin to the dimensions ofthe levers. By suita le de- SU'SPIEITSION OF RAIL-GAR BODIES ANDTHELIKE.

it therefore, the spring 6 may be caused tosupport only a smallproportion of the total weight of the coach. If the vehicle in roundinga curve should tend to cant toward one side, say toward the left, theroller 4 on that side will be depressed and the lever 3 will rotate a.little. On the opposite side the roller can rise and the lever 3 canrotate in the opposite direction. The result of these movements it willbe seen is to move the whole springfi, the socket plate 7, the kingpivot 8, and the Whole vehicle-frame 9 toward the right, thus bringing agreater proportion of the weight upon the right hand roller 4 andtending to restore the body to its horizontal position.

It will be obvious that the design of the levers 3 may be varied; forexample the levers could be straight instead of being bell crank levers.In this case, however, unless the levers are inclined there would be notendency to move the vehicle bodily to the right when it tilted to theleft; but the dis tribution of weight between the pivot pin and the siderollers would be secured just as in the'construction described. Anordinary standard king pinand center plate may be used instead of thespherical pin and socket referred to above. that the positions of thespherical pin and the socket might very conveniently be reversed so thatthe former instead of the latter forms part of the bogie bolster.Finally, the laminated springs might be replaced by a beam supported onthe links and carrying a number of suitable springs which would in turnsupport the spherical pin or socket plate.

What I claim is:

1-. In a bogie vehicle the combination with the bogie main frame oflevers pivoted thereon transverse to the vehicle, a main It is evidentalso frame resting on one end of said levers and thereon having inclinedarms, a vehicle body resting in part on one end of said levers and aresi body resting uponi the ends of the inclined arms of said levers.

4. In a'bogie vehicle the combination with a bogie main frame of leverspivoted thereon, links depending from the inner end of said levers, aspring connecting and resting on said links, and a main vehicle bodyresting in part on said spring and in part upon the outer ends of saidlevers.

5. In a bogie vehicle the combination with a bogie main frame of' leverspivoted thereon having inclined inner arms, links depending from theinner end of said levers, a spring connecting and resting on said links,and a main vehicle body resting in ient supportat the center of saidpart on said sprin and in part upon the outer ends of said fevers.

6. In a bogie vehicle the combination with a bogie main frame of leverspivoted thereon, links depending from the inner end of said levers, aspring connecting and resting on said links and a pivoted support forsaid vehicle body resting on said sprmg, and a main vehicle body restingin part on said sprin and in part upon the outer ends of said evers.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
